Fig. 2 is asecjournal 9 with a journal 12, projecting a suittional view taken onthe line 2 2 of Fig. 1 deable distance beyond the end of the roller,signed to show the arrangement of gears and and on the end of which isfixedly secured a 50 the location of the rollers with respect to thesmall gear-wheel 13. The journals 12 are adapted to be received and seatin the bottoms of the slots 10, so that the gears 13 will be locatedoutside of the bracket 4. Secured to and projecting from the outer faceof the bracket 4, provided with the slots 10, are two studs 14 15,respectively, each of which is interiorly screw-threaded. On the stud 14is rotatably mounted a gear 16, in mesh with the small gear-wheel 13 onone of the rollers. Said gear is held on its stud by means of a Washer17, placed against the outside thereof, and a screw 18, passed throughsaid Washer and engaging in the sore w-threads of the stud.

19 indicates a large disk, having its periphery milled, as indicated at20, fixedly secured to the inner side of which is an operatinggear 21.disk and operating-gear, and said gear and disk are designed thereby tobe mounted on the stud 15, so that the operating-gear 21 shall mesh withthe gear 16 and the small gear-wheel on the other roller. The disk 19,-with its operating-gear, is retained on the stud 15 by means of a washerand a screw in the manner described with reference to the gear 16. Thegear 16, it will be seen, is merely an intermediate gear connecting theoperating-gear 21 with one of the gears on one of the rollers. Inassembling the parts of the apparatus the rollers are first placed inposition in the brackets 4 in the manner described, after which theintermediate gear 16 and the combined disk and operatinggear 19 21 areinserted on their respective studs. The outward incline of the slots 10tends to prevent any upward displacement of the rollers 11 in theoperation of the device, as will be understood; but to further centerthese rollers and to hold their gears in fixed relation with theintermediate gear 16 and operating-gear 21, respectively, and preventall binding and undue wear I employ a retaining-plate 25. (Shown indetail in Fig. 6.) The plate 25 is of substantially the same length andheight as the bracket 4 and is provided near each end with an enlargedrecess 26, opening from the bottom. Near the top of the plate and ateach end are provided two outwardly-projecting tongues 27 28,respectively, which are formed by cutting the metal at two places andthen bending the intermediate portion of the metal outward. The bracket4, containing the slots 10, is provided near its top and at each sidewith a recess 29 30, respectively, the recess 29 being longer than therecess 30. In placing the plate in position it is inserted between theends of the rollers and the bracket 4, the recesses 26 passing over therespective journals 12 of the rollers. As shown in Fig. 4, the recesses26 are of much greater width than said journals, so that the plate 25may be moved to one side or the other. The plate having been placed inposition in the manner just described it is moved to one side andpressed down at one end, so that the tongue 27 may be inserted in therecess 29. It is then moved to one side An aperture 22 passes throughsaid in the opposite direction, bringing the tongue 27 substantially tothe end of the recess 29, and then the opposite end of the plate ispressed down to bring the tongue 28 opposite the recess 30, after whichthe plate is moved laterally to cause said tongue 28 to enter the recess30. Such movement of the plate, however, will not cause the tongue 27 tobe moved out of the recess 29 owing to the difference in length of therecesses 29 and 30. When thus placed in position, the tops of therecesses 26 in said plate will engage the journals 12 and prevent themfrom rising, while slots 10 will prevent movement laterally of saidjournals.

31 indicates the web, opposite ends of which are secured to therespective rollers 11 and wound thereon in such manner that one rollerwill display one side of the Web, while the other roller will displaythe opposite or under side. In other words, the web passes from theunder side of one roller to the upper side of the other.

The rollers and the operating mechanism having been mounted on the base2 in the manner described, said base may now be inserted in the casing land is screwed in position by the screws 3. The casing 1 is providednear one end with a transverse slot 32, through which the winding-disk19 may protrude. The said casing is also provided on its upper side withan index or scale, which may be made from cardboard or any othersuitable material and is indicated generally,

by the numeral 33, said scale or index being provided with twolongitudinal slots or sightopenings 34 35, respectively, which extendimmediately over and along the rollers 11, containing the web 31. Thesight-openings 34 35 correspond and register with similar openings madein the top of the casing, as

will be understood, the scale-card or index being pasted or otherwisesecured to the top of the casing. The said scale 33 will preferably becovered with some transparent material, such as glass or celluloid 36.

In the preferred embodiment of the invention, as illustrated herein, Iarrange in a column adjacent to one edgesay the left-hand edge of eachsight-opening or slot 34 35a column of figures which indicate differentweekly salaries, such column being indicated by 37, while to the left ofthis column is-arranged a second column 38, indicating the rate perhourof the wages. To the right of each sight-opening are arranged threecolumns of figures 39, 40, and 41, indicating, respectively, the rate ofsalary'forone-fourth, one-half, and three-fourths of an hour. In thecenter of the scale is provided a space 42, which is utilized fordesignating in a suitable manner these various columns. Thus in Thecolumn 38 is designated by the The columns 39, 40,

lIO

cated in the space 43 in the line of a given column of numbers on theweb. The web 31 is correspondingly numbered on both sides, and inoperation two columns of numbers on the web may be made to appearsimultaneously at each of the openings 34 35, and each column thus madeto appear will disclose the same number in the central space 43. In thearrangement of the scale and of the two columns of figures which aresimultaneously disclosed by the web the column of figures on the web atthe right of the device and the columns of figures arranged with respectto the aperture through which said column is disclosed are continuationsof a like arrangement of numbers at the left of the devicethat is tosay, the combined arrangement of numbers at the right begins at the topwhere the combined arrangement of numbers left off at the bottom of thecolumn at the left. The principle is precisely the same as though onlyone roller were employed; but two rollers displaying two columns ofnumbers are employed for the purpose of affording greater amplitude ofcomputation., In the same manner four or more rollers could be employedto display a corresponding number of columns of figures. The numbers onthe web and scale are based on a day of ten hours, and a singleillustration will suffice to show the use of the device.

Supposing it be desired to find the amount due an employee who hasworked fifty-seven hours and receives a salary of fifteen dollars perweek for ten hours a day. To ascertain this, the disk 19 is turned untilthe number 57 in the space 43 in the center of the web appears at thesight-openings 34 35. The operator then runs his eye down the column ofnumbers 37, which contains numbers indicating different weekly salaries,until 15.00 is reached. Opposite 15.00 on the column of numbers on theweb will be displayed the numbers 14.25, which will indicate the amountdue the workman. If the employee had worked fifty-seven and one-fourthhours, then the operator would refer to the first column to the right,indicated by 39, and opposite 14.25 he would find 6, which amount wouldbe added to 14.25. If the time worked was fifty-seven and one-halfhours, he would refer to the column 40, and opposite 14.25 he would find13, which amount would be added to the 14.25. If

the time worked was fifty-seven and threefourths hours, he would referto the column 41, and opposite 14.25 would find 19, which amount wouldbe added to 14.25,

thus giving the total amount due for fifty- 1 seven and three-fourthshours work. The large numbers at the center of the web indicate thetotal number of hours or work. If the salary is based on a rate perhour, then the operator would simply refer to the column 38 to ascertainthe salary due in place of the column 37that is to say, using the samenumbers as in the above illustration. If an employee had workedfifty-seven hours and received twenty-five cents an hour for his work,the amount shown to be due is 14.25. As stated, however, otherarrangement of numbers may be employed, and I have described andillustrated an arrangement with which my invention was particularlydesigned to be operated.

It will be noted that the size of the rollers 11 is such as to bring theweb into close proximity to the openings 34 35in the top of the casingwithout the use of any other form of guide or supporting device.
